Background
Alfred Hassner was born in Czernowitz and spent World World War II in hiding while he lost his father. After the war he returned to study in Vienna and then immigrated to the United States of America where he continued his studies.
(Synthetically useful organic reactions or reagents are of...)
Synthetically useful organic reactions or reagents are often referred to by the name of the discoverer(s) or developer(s). Older name reactions are described in text books, but more recently developed synthetically useful reactions that may have been associated occasionally with a name are not always well known. For neither of the above are experimental procedures or references easy to find. In this monograph approximately 500 name reactions are included, of which over 200 represent newer name reactions and modern reagents. Each of these reactions are extremely useful for the contemporary organic chemistry researcher in industry or academic institutions. This book provides the information in an easily accessible form. In addition to seminal references and reviews, one or more examples for each name reaction are provided and a complete typical experimental procedure is included, to enable the student or researcher to immediately evaluate reaction conditions. Besides an alphabetical listing of reactions and reagents, cross references permit the organic practitioner to find those name reactions or reagents that enable specific transformations, such as, conversion of amines to nitriles, stereoselective reduction, fluoroalkylation, phenol alkynylation, asymmetric syntheses, allylic alkylation, nucleoside synthesis, cyclopentanation, hydrozirconation, to name a few. Emphasis has been placed on stereoselective and regioselective transformations as well as on enantioselective processes. The listing of reactions and reagents is supported by four indexes.

Since the publication of "Organic Syntheses Based on Name Reactions and Unnamed Reactions"(Volume 11 in the Tetrahedron Organic Chemistry series), there has been a proliferation of discoveries of name reactions in the field of organic chemistry. Hence, this, the second, revised, edition of the text has focused on the ongoing development in this area of research. The revised title reflects the notion whereby many new reagents and reactions are now being referred to by their names. The inclusion of over 155 new stereoselective and regioselective reagents or reactions including asymmetric syntheses, brings the total to over 540. Features that should be valuable to the reader include over 3000 references, a names index, reagent index, reaction index and a functional group transformation index. The latter of these indexes will allow the reader to search for conversions of one functional group to another and has proved a much utilized tool for the synthetic chemist, searching for pathways to perform synthetic procedures.

Organic Syntheses Based on Named Reactions is an indispensable reference companion for chemistry students and researchers. Building on Hassner & Stumer’s highly regarded 2e, this new work reviews 750 reactions, with over 100 new stereoselective and regioselective reactions. Each A-Z entry provides a carefully condensed summary of valuable information that a chemist needs to understand and utilize these fundamental reactions in their work, including brief practical details. The book is illustrated with real synthetic examples from the literature and about 3,400 references to the primary literature to aid further reading. Extensive indexes (name, reagent, reaction) and a very useful functional group transformation index help the reader fully navigate this extensive collection of important reactions. With its comprehensive coverage, superb organization and quality of presentation, this long-awaited new edition belongs on the shelf of every organic chemist. • Handy reference guide that explains 750 established named processes and methods that are trusted and used by organic chemists to synthesize or transform molecules • Provides key data on each transformation including background, mechanism and--uniquely to books in this area--experimental details • Extensive and multiple indexes allow the reader to search for information as and how they want and to rapidly plan transformations

Alfred Hassner was born in Czernowitz and spent World World War II in hiding while he lost his father. After the war he returned to study in Vienna and then immigrated to the United States of America where he continued his studies.
Bachelor of Science, University Nebraska, 1952. Doctor of Philosophy, University Nebraska, 1956.
Hassner is currently Emeritus Professor at Bar Ilan University. After a postdoctoral at Harvard University, Hassner in 1957 joined the University of Colorado Boulder where he became full professor in 1966. In 1975 he was called to State University of New York Binghamton as Leading Professor and in 1983 he moved to Bar Ilan University in Israel.
Hassner was visiting professor at Wuerzburg University, Stanford University, Weizmann Institute of Science, University of California Berkeley, University of Nijmegen, Universite Claude Bernard Lyon, Indian Institute of Science Bangalore, Kyushu Institute of Technology.
Research
Professor Hassner’s research group has studied: Regioselective additions of pseudohalogens. Stereochemistry of reactions of azides and organic nitrogen functions.
Development of catalysts like DMAP for direct esterification of hindered alcohols. Regiochemistry of 3+2 cycloadditions and of 2+2 ketene olefin cycloadditions.
Reaction of 3-member-ring iodonium ions and of nitrilium ion intermediates.
Reactions of steroids. Organosilanes, Photochemical protection, Medicinal chemistry, electrophilic amination. Hassner’s group pioneered in methodology for synthesis of small ring heterocycles such as aziridines, azirines, azetines, as well as of larger ring heterocycles including azepines.
Recently they studied TiCl catalyzed reactions.
